This wing 5 portion is provided with a vertically disposed, longitudinally extending slot -.-which is""extended at-one side, as shown at 31, at apoint intermediate its length. This widened po'rtion of the slot permitsthe passage of thebent over terminal 25 .ofthelocking-arm infir stassembling the fastener and ,the ;slot. 1 is so formed: and the. retaining memberQZG soapositioned that by proper sexin of the locking arms at their hinged 15 :joints, the locking arms may bemoved back and forth through'the slot to either close the storm sash ;or to open it to any desired exltent' within; the limit of .the ength of the arms; *Obviously, thisfastener, in addition to{ the closed. position of the jsash, admits .of as manyllopen positions or the sash as v ther'e arefvhingedlmembers'rin thearms. In -the"drawings, I have illustrated locking ;,arms j haying 5 three members hingedly conz5'fnected' and the sash 1nay, :therefor'e,' be, either closed, .fully opened, gonethird fopened. or

two-thirds,:OPQne,d,' as preferred I 1 any of/the j'opeii positions of' the sash, the looking armsfare so manipulated'as to cause 'theirnotches. 24 to engage the retaining members at the lower ends of their slots 30. Obviously, as each member of the locking arms is drawn inwardly-through its retaining member t'o' elose orjpartiall'y close the stormlsaslnfthey may be. swung either up- 'wardly' for downwardly in parallel relation to" the; parting beads j1 5 in {order that they ym no way interfere with the opening and closing of"f thelower, sash: proper 12 of n Fig. 1 andialso in Fig. 2. Injfully closed position of the storm sash, the ears '119 of the brackets 16 extend through the slots 30 of the retaining devices 29 and thefentire loeking arms are swung into; parallel relation' rtefthebeads. filn order to lock the sash in; this position, I provide each of the side 1 (bars of itheistorm sash with a retaining'fda vice' 132 est shown; in Fig; 3 of the drawings. 12Ihis' 31911 1 5 n 'i j 1 d.@ dy m r j hea sheet metal, one. arm; of which is peri "atedftofreoeivea iscrewf33gby :nieails. of

the Window,', this. being clearly illustrated in notchesof these arms with the retaining members and also the engagement of the upturned arm members against the inner face of the wing portions 29 of the retaining members when the storm. sash is in any position, except fully openposition, and the locking engagement between the notches and retaining member and between 'the winged port-1011 thereof and the laterally bentterminals 25 of the locking arms 29,;

.. when the storm sash is iii-fully open position, it is practically impossible for the sash to be blown loose. I V Itshould be noted that inasmuch as the locking arms21 are resilient, the said arms maybe attached to the sash and the retain: ing. members 26 attached to the, window cas- 5 ing in such a manner that there is a constant tendency for the ,arms tospring laterally into the lateral extensions 31 of the slots 30. It will, therefore, be seen that when the arms aremoved throughthe slots 30, until ,one of their notches is in vertical alinement Qwith the lower end of the slot, the arms may swinglaterally into the extensions 31, the notches engagingthe lower edges of such extensions instead of the lower edges of the slots proper and the arms being held against upward 'movement which would free the notches by their engagement with the up- Per edges of the extensions 31 of the slots. The arms will, therefore, be locked in position until swung laterally against their nat- =ura1 resiliency.

It will of course be understoodthat I do not wish to be limitedto the specific. de- 1 tailsiof construction, illustrated and de- 7 scribed, as various minor changes, Within the scope of the appended claims, may be ."made atYany time, without in the slightest "degree departing from the spirit of my invention. .v i I- Havingthusdescribed the invention, what is claimed as new is: i .r Asfastener for swinging sashes includ- Qing fanx arm adapted to'abe pivotally .eonneetedto the sash and having its lower face 1 notched, and. arctaining member adapted to be securedito a window casing and formed witha vertiealslot through which the ariu hers, each provided in its lower edge with a notch adjacent that end more remote from the bracket and a retaining member in the form of an L-shaped plate adapted to be secured to a Window casing, one Wing of the erally, whereby the arm may spring into 1 the widened portion When one of its notches is in vertical alinement.

In testimony whereof I affix my signature" in presence of tWo Witnesses.
